What is the kenetic energy of a 3-kilogram ball that is rolling at 2 meters per second?

∙ 12y ago
Kinetic energy = (1/2)mv2, where m is mass and v is velocity.
In this case, mass is 4 kg and velocity is 5 m/s, so K = (1/2)(4)(5)2 = 50 Joules.
(The units of energy are Joules, as long as everything is measured in kilograms, meters, and seconds.)

The kinetic energy of the ball can be calculated using the formula KE = (1/2)mv^2, where m is the mass of the ball (3 kg) and v is its velocity (2 m/s). Plugging in these values, we get KE = (1/2)(3 kg)(2 m/s)^2 = 6 Joules.

KE = 1/2(24 kg)(2 m/s)2
= 48 Joules

∙ 12y agoKinetic Energy (KE) can be represented by the following formula: KE = 0.5mv2.
In this case kinetic energy would equal 480,000 joules.

What types of meters are used in Energy Management Systems?
The most commonly used meters in Energy Management Systems are electricity meters, gas meters, and water meters. These meters measure the consumption of energy and resources in buildings and facilities, providing data that is crucial for monitoring and optimizing energy usage. Advanced meters, such as smart meters, are also becoming more widely used for their ability to provide real-time data and enable more precise energy management.
A 5kg object is being lifted to a height of 8 meters and is dropped what is the kinetic energy of the object at 2 m?
To find the kinetic energy of the object at 2 meters height, we need to consider the conservation of energy. At a height of 2 meters, the object will have potential energy of mgh = 5kg × 9.81m/s^2 × 2m = 98.1 Joules. Since no external work is being done on the object, this potential energy will be converted into kinetic energy. Thus, the kinetic energy of the object at 2 meters height will be 98.1 Joules.
How many meters will a photon of light energy travel in one nanosecond?
In one nanosecond, a photon of light energy will travel approximately 0.3 meters in a vacuum, which is the speed of light.
What is the product of the force and the distance?
torque
What is Load survey recorders energy meters?
Load survey recorders energy meters are devices used to measure and record electricity consumption over a specified period. They are typically used by utility companies, businesses, and homeowners to monitor energy usage patterns, identify peaks, and optimize energy efficiency. These meters help track energy usage data for billing, analysis, and planning purposes.
Is touching a kinetic energy?
Kinetic energy is the energy of motion. Your touching finger has mass and is moving some meters per second, so that motion is kenetic energy.
How much kenetic energy of 1000 kilogram car traveling of 50 kilometer per hour?
Convert the speed to meters/second (dividing km/h by 3.6 gives you m/s), then insert the numbers into the standard formula for kinetic energy (1/2 m v2).
How many joules of kenetic energy does 1 kg book have when it is tossed across the room at a speed of 2 miles per second?
Needs conversion. 2 m/s (1609 meters/1 mile) = 3218 meters per second ( fast!! ) Kinetic Energy = 1/2(mass)(velocity in meters per second)^2 KE = 1/2(1 kg)(3218 m/s)^2 = 5177762 Joules ( 5.2 X 10^6 Joules ) --------------------------------------------------

How does a waves energy affect its amplitude?
The energy of a wave is directly proportional to its amplitude. Higher energy waves will have larger amplitudes, while lower energy waves will have smaller amplitudes. This relationship is described by the wave equation and is a key characteristic of wave behavior.
What is the product of the force and the distance?
torque
Why watts is used in consumer power meters?
Consumers do not normally have 'power meters'; they normally have 'energy meters', which are used measure the amount of energy being purchased from the electricity supply company. 'Power meters' are wattmeters, which measure power -i.e. the rate at which you use energy. Energy meters measure energy in units called kilowatt hours, whereas wattmeters measure power in watts. Your electricity supply company isn't really interested in the power of your residence, only the energy consumed.
